Official Title: Optimizing Light Wavelength for Treatment of Seasonal Affective Disorder
Brief Summary:
The specific aim of this study is to test the hypothesis that light stimuli concentrated around 467 nm will evoke a significantly stronger therapeutic response in SAD patients compared to light stimuli concentrated around 657 nm at an equal photon density.
The secondary objective of this study is to determine the efficacy of different colors and levels of light in order to optimize therapeutic benefit, while also minimizing side effects and maintaining safety of light exposure.
